The type of photography that you are planning to use is an important decision factor. Here we have evaluated the TTArtisan 14mm F2.8 and the Canon 10-18mm f4.5-5.6 IS STM for their suitability to various photography scenarios:
Size and Weight Comparison
The size of a lens is a crucial factor to consider when comparing two lenses. TTArtisan 14mm F2.8 is the longer of the two lenses at 75mm. The Canon 10-18mm f4.5-5.6 IS STM with a length of 72mm, is 3mm shorter. On the other hand, the Canon 10-18mm f4.5-5.6 IS STM has a larger diameter of 75mm compared to the TTArtisan 14mm F2.8's 65mm diameter.
The weight of a lens is equally significant as its external dimensions, particularly if you intend to handhold your camera and lens combination for extended periods. Canon 10-18mm f4.5-5.6 IS STM weighs 240g, 45% (197g) lighter than the TTArtisan 14mm F2.8's weight of 437g.
Filter Threads
The TTArtisan 14mm F2.8 has a filter size of 77mm whereas the Canon 10-18mm f4.5-5.6 IS STM has a 67mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 77mm filters that we recommend you to consider for the TTArtisan 14mm F2.8:
And these are the 67mm filters that we recommend for the Canon 10-18mm f4.5-5.6 IS STM:
